The Guard is a 2011 English-language Irish comedy film written and directed by John Michael McDonagh, starring Brendan Gleeson, Don Cheadle, Mark Strong and Liam Cunningham. It is the most successful Irish film of all time in terms of Irish box-office receipts, overtaking The Wind that Shakes the Barley (2006) which previously held this status. Sergeant Gerry Boyle (Gleeson) is an officer of the Garda Síochána in Connemara in the west of Ireland. He is crass and confrontational, regularly indulging in drugs and alcohol even while on duty. He is also shown to have a softer side, showing concern for his ailing mother, Eileen (Flanagan). Boyle and his new subordinate, Aidan McBride (Keenan), investigate a murder in their jurisdiction, with evidence apparently pointing to an occult serial killer. Shortly after, Boyle attends a briefing by FBI agent Wendell Everett (Cheadle), sent to liaise with the Garda in hunting down four Irish drug traffickers, led by Francis Sheehy-Skeffington (Cunningham), who is believed to be awaiting a delivery of cocaine coming into Connemara by sea.
